Its working great for non-ROOT named war files and will deploy and direct new user sessions to the newest version of the web-app, without having to restart Resin.
For the ROOT web-app, however, I have to restart Resin in order for it to recognize the latest version
i.e. If I copy an updated war into webapps like ROOT-1.2.2.war, it will deploy the war file but new user sessions are still directed to the old version.

Is this functionality restricted to only non-ROOT web-apps or is this a bug?
